Characterizing the Brain - Cell by Cell

My group develops approaches to study cell-to-cell signaling in the brain – how the cells of the brain talk to each other. The brain is heterogeneous, probably more so than any other organ in our body, and many of its functions depend on the unique characteristics of these cells.

Researchers discover human factor that drives maturation of helper T cells

A powerful arm of the immune system is production of antibodies that circulate through the blood and neutralize invading pathogens. Although B cells actually manufacture antibody proteins, the process is aided by neighboring T cells, which shower B cells with cytokines to make them churn out high-quality antibody proteins--and remember how to do so.
